Patient Data

Case Discussion

The prevalence of appendicitis in patients who present with abdominal pain to the emergency department is approximately 14%.

Traditionally, acute appendicitis has been diagnosed on the basis of clinical findings.

CT is highly sensitive (94 - 98%) and specific (up to 97%) for the diagnosis of acute appendicitis, and allows for alternative causes of abdominal pain to also be diagnosed. In this case, a simple non-contrast study, as institution protocol, was enough to determine the diagnosis.
